PRINTED ANTENNA Russian patent published in 2010 - IPC H01Q9/04 

FIELD: radio engineering.

SUBSTANCE: in printed antenna which contains lower dielectric layer (1), upper dielectric layer (2), lower metal layer (3) located on lower surface of lower dielectric layer (1), middle metal layer (4) located between upper dielectric layer (2) and lower dielectric layer (1) and upper metal layer (5) located on upper surface of upper dielectric layer (2) and excitation elements (8), there introduced are four connection straps (6) connecting upper metal layer (5) and lower metal layer (3) without electrical contact to middle metal layer (4), and crossed slot (7) is made in upper metal layer (5).

EFFECT: decreasing dimensions, providing reception and transmission of waves with circular polarisation at maintaining working frequencies.
